# OF POINTS TO ANALYSE:
VALIDATE YOUR DATA BEFORE SUBMITTING TO AVOID RESUBMITTING
SUBMIT DATA:
the results of the analysis are presented in the following format:
- the equation of the estimated line of regression between the points analysed:
Ý = a + bX
where:
Ý : dependant variable or the estimate of Y
a: Y intercept
b: slope of the regression line
X: independant variable
The equation is obtained by 'minimizing' the 'errors' between the estimated points on the regression line and the points actually analysed
"Se"
:
-
It's the standard error of estimate between the points on the regression line and the points analysed; the regression line +/- 1Se, +/- 2Se or +/- 3Se
should include 68%, 95.5% or 99.7% of the points analysed.
The data will be captured by a table of 100 entries (25 rows by 8 columns(2 columns per point))
The program is designed to handle 'real' numbers and please include more that 30 points for the analysis since the Student distribution is not supported
